Math: 3D Shapes Sphere Cube Cone and Cylinder

Identify and describe simple solid shapes

Math - Grade K-1

Instructions: Read each problem carefully. Name the 3D shape or describe what you notice. Show your work in the space provided.
  1. 1

    A ball is shaped like which 3D shape: sphere, cube, cone, or cylinder?

    Think about a shape that can roll in any direction.

    A ball is shaped like a sphere because it is round all over.
  2. 2

    A box with all flat square faces is shaped like which 3D shape?

    A box with all flat square faces is shaped like a cube.
  3. 3

    A party hat is shaped like which 3D shape: sphere, cube, cone, or cylinder?

    Look for the shape with one point at the top.

    A party hat is shaped like a cone because it has a point and a round flat bottom.
  4. 4

    A soup can is shaped like which 3D shape?

    Think about a shape with a circle on the top and a circle on the bottom.

    A soup can is shaped like a cylinder because it has two flat circles and one curved side.
  5. 5

    Circle the shapes that can roll: sphere, cube, cone, cylinder.

    A shape can roll if it has a curved part.

    The sphere, cone, and cylinder can roll because they have curved surfaces.
  6. 6

    Which 3D shape has 6 flat square faces?

    A cube has 6 flat square faces.
  7. 7

    Which 3D shape has no flat faces and no corners?

    Think about the shape of a ball.

    A sphere has no flat faces and no corners.
  8. 8

    Which 3D shape has one point and one flat circle?

    A cone has one point and one flat circle.
  9. 9

    Which 3D shape has two flat circles, one on top and one on bottom?

    Think about a can or a paper towel roll.

    A cylinder has two flat circles, one on top and one on bottom.
  10. 10

    Look at these objects: ball, dice, ice cream cone, can. Write the 3D shape name for each object.

    Match each real object to the 3D shape it looks like.

    The ball is a sphere, the dice is a cube, the ice cream cone is a cone, and the can is a cylinder.
  11. 11

    Which shape is best for stacking neatly: sphere, cube, cone, or cylinder?

    A cube is best for stacking neatly because it has flat faces.
  12. 12

    Draw a line to match each shape name to an object: sphere to ball, cube to block, cone to party hat, cylinder to can.

    Look at the shape of each object before you match it.

    Sphere matches ball, cube matches block, cone matches party hat, and cylinder matches can.
  13. 13

    A shape has flat faces and corners. It does not roll. Is it a cube or a sphere?

    It is a cube because a cube has flat faces and corners, and it does not roll easily.
  14. 14

    A shape has a curved side and can stand on a flat circle. Is it a cone or a cube?

    A cube has square faces, not a curved side.

    It is a cone because a cone has a curved side and can stand on its flat circle.
  15. 15

    Find one object in the classroom or at home that looks like a sphere, cube, cone, or cylinder. Write the object and its shape name.

    One possible answer is that a ball is a sphere. Other correct answers may name an object that matches a sphere, cube, cone, or cylinder.
